Muon Storage Ring Neutrino Sources:
A Brief History/Bibliography
A. Early History: Muon storage ring source in which energetic
pions are injected into a ring, decay to produce muons captured
within the ring, which in turn decay -> neutrino beam. This idea
was proposed several times, but has the basic problem that the
neutrino beam intensity is low.
1. D. G. Koshkarev, "Proposal for a decay ring to produce
intense secondary particle beams at the SPS",
Synopsis: Proposed a general ring to capture pi/K and
allow them to decay. Considered neutrino beams, including
those from the muon decays. Calculated fluxes, although
not with the correct expressions for muon decay. The fluxes
were very small. Physics motivation not considered.
2. D. Cline and D. Neuffer, "A muon storage ring for neutrino
oscillation experiments", AIP Conf. Proc.. 68, 846 (1980).
Synopsis: Proposed exploiting the FNAL antiproton debuncher
as a muon decay neutrino source with a 100 ton detector 0.5 km
from the source. Quotes event rate. Does not consider physics
potential. Ascribes idea to:
2a. Stan Wojcicki, unpublished (1974), and
2b. T. Collins, unpublished (1975).
3. W. Lee (spokesperson) et al., FNAL Proposal P860, "A Search for
neutrino oscillations using the Fermilab Debuncher", 1992.
Synopsis: Proposed experiment at the FNAL antiproton debuncher
as a muon decay neutrino source for a short baseline search for
nu_e -> nu_tau oscillations. Considered physics case, and presented
fluxes and interaction rates. However, these were marginal, and
the experiment was not approved.
B. Modern Ideas: The neutrino factory. Muons are created from an
intense pion source at low energies, their phase space compressed
to produce a bright beam which is then accelerated to the desired
energy and injected into a storage ring with long straight sections
pointing in the desired direction. This can produce very high
intensity neutrino beams.

and physics potential", FERMILAB-PUB-97-389, 1997; Presented in
the Workshop on Physics at the First Muon Collider and Front-End
of a Muon Collider, November, 1997, and Published in
Synopsis: Proposed using a muon source of the type being developed
for muon colliders, coupled with a muon storage ring neutrino source.
Calculated fluxes and rates versus baseline length, muon energy, angles,
and polarization. Considered oscillation physics potential. Proposed
tilting the ring at large angle to shoot through the Earth. Proposed
searching for nu_e -> nu_mu and nu_tau oscillations by searching for
wrong-sign muons. Proposed exploiting the muon polarization to turn
on/off nu_e processes. Rates large and physics reach interesting.
Pointed out that at high energies, event rates are very large enabling
neutrino physics with small and highly instrumented detectors.
